Purpose: The purpose of this study was to examine the relationships among perceived health status, exercise self-efficacy, social support, and exercise compliance and factors influencing exercise compliance in older adults in an area. Methods: The sample consisted of 154 older adults who attended a senior welfare center in D metropolitan city. Data were collected from the 25th to the 31th of January in 2012. Results: The mean score for perceived health status was 2.94, 911.69 for exercise self-efficacy, 46.99 for social support, and 6.83 for exercise compliance. The highest score on social support domains was emotional support, followed by self-esteem, material, and informational support. There were significant correlations between perceived health status and exercise self-efficacy, between perceived health status and exercise compliance, between exercise self-efficacy and social support, between exercise self-efficacy and exercise compliance, between emotional support and exercise compliance. Findings of multiple regression indicated that only exercise self-efficacy significantly explained exercise compliance. Conclusion: Health care providers may need to develop various intervention program to promote exercise self-efficacy in order to influence on exercise compliance and adherence among older adults.

The safety assessment for facility industry is now being periodically performed. For the purpose of scientific safety management, QRA(Quantitative Risk Assessment) is also being performed, and reliability data of the facilities is essential to perform the assessment. Generally, the existing safety assessment is performed by using the values announced in other industry processes, which result in the drop of reliability. In order to solve this problem, there is an urgent need to establish reliability database for the facilities. The most appropriate method is to perform a direct reliability analysis towards the facilities undergoing safety assessment. In this study, in compliance with the assessment method and procedure of OREDA-2002 handbook, the facility reliability data are collected, which include the calendar time and operational time in terms of different facility items, the number of failures in terms of different failure mode, the mean, standard deviation, lower limit and upper limit of failure rate, and the failure rate. And the data process method for this special occasion is also proposed when the number of failure is 0.

In this system, mobile devices are not independent, they can communicate with each other, one device's change can affect the whole system or other devices. To achieve the above mentioned A Self-Reconfigurable System of Contents, through discover the device and connect process, to establish the connection between the mobile devices. After user assigns two dimension display type, the user can select content to input the system, contents are portioning and broadcast to devices. The system can self-reconfigure contents rapidly and exactly. This technique supports contents self-reconfiguration for devices remove, addition and position exchange. In this paper, when the user uses the hand contacts device, the device sends a signal to assist the system to detection device's position. The system does not need to get accurate devices moving direction, just according to all changed devices position to judge where the devices destination is. This research develops an application according to this technique, and the real machine tests the application using Android platform. Some communication protocols and mathematical modeling methods are proposed. These methods can also be used in other Internet of Things (IoT) fields, such as Drones Navigation, Smart Home, and Informational City management.

Purpose: The purposes of this study were to identify the perceived nursing needs and the differences by general characteristics of parents of infants in a neonatal intensive care unit (NICU) and to provide useful evidences developing a new intervention for family-centered care in NICU. Methods: A convenience sample of 121 parents of infants in NICU was used and the participants asked to complete the Korean version of NICU Family Needs Inventory (NFNI) from April to May, 2014. Data were analyzed using descriptive statistics, t-test and ANOVA. Results: The participants reported high average score in the perceived nursing needs. In subscales, needs for assurance rated highest score and needs for information, proximity, support, and comfort were followed. Mothers reported higher nursing needs score than fathers except the subscale of support. Conclusion: The findings suggest that nurses in NICU actively provide information about treatment, nursing, results of laboratory tests, and current status to give reassurance to parents. Not only providing informational support of parents of NICU infants, but also finding methods to contact to parents is necessary. In addition, nurses need to provide optimized intervention in current healthcare system and hospital environment.

Background: The study aimed to assess complementary and alternative medicine (CAM) use and their associated factors with breast cancer patients in Bandung, Indonesia. Materials and Methods: In total, 330 breast cancer patients were administered questionnaires on their CAM use and CAM predictive factors including socio-demographic parameters, clinical data and quality of life, trust in physicians, trust in hospitals, satisfaction and informational needs. Data were analyzed using univariate analysis and multivariate log regreesion analysis. Results: Overall 33.3% of patients reported use of CAM. Lower income, lower education, presence of metastasis, prolonged diagnosis, less trust in physician were found to be highly associated with CAM use. Conclusions: CAM use by breast cancer patients can be interpreted as an attempt to explore all possible options, an expression of an active coping style, or expression of unmet needs in the cancer care continuum. Physicians need to openly discuss the use of CAM with their patients and identify whether they have other unmet supportive needs.

Purpose - The volume and valence of online word-of-mouth(eWOM) have become an important part of the retailer's market success for a wide range of products. This study aims to investigate how the growth of eWOM has generated the product's final financial outcomes in the introductory period influences. Research design, data, and methodology - This study uses weekly box office performance for 117 movies released in the South Korea from July 2015 to June 2016 using Korean Film Council(KOFIC) database. 292,371 posted online review messages were collected from NAVER movie review bulletin board. Using regression analysis, we test whether eWOM incurred during the opening week is valuable to explain the last of box office performance. Three major eWOM metrics were considered after controlling for the major distributional factors. Results - Results support that major eWOM variables play a significant role in box-office outcome prediction. Especially, the growth rate of the positive eWOM volume has a significant effect on the growth potential in sales. Conclusions - The findings highlight that the speed of eWOM growth has an informational value to understand the market reaction to a new product beyond valence and volume. Movie distributors need to take positive online eWOM growth into account to make optimal screen allocation decisions after release.

Recently, many enterprises have attempted to construct data warehousing systems for decision-support. Data warehouse is an intelligent store of data that can aggregate vast amounts of information. Building DW requires two important development issues:(i) DW for the decision making of business users and (ii) metadata within it. Most DW development methodologies have not considered metadata development; it is necessary to adopt a DW development methodology which develops a DW and its metadata simultaneously. Metadata is a key to success of data warehousing system and is critical for implementing DW. That is, metadata is crucial documentation for a data warehousing system where users should be empowered to meet their own information needs; users need to know what data exists, what it represents, where it is located, and how to access it. Furthermore, metadata is used for extracting data and managing DW. However, metadata has failed because its management has been segregated from the DW development process. Metadata must be integrated with data warehousing systems. Without metadata, the decision support of DW is under the control of technical users. Therefore, integrating data warehouse with its metadata offers a new opportunity to create a more adaptive information system. Therefore, this paper proposes a DW development methodology from a metadata perspective. The proposed methodology consists of five phases: preparatory, requirement analysis, data warehouse (informational database) development, metastore development, and maintenance. To demonstrate the practical usefulness of the methodology, one case is illustrated
